Abstract: There has been some attempt to predict rainfall recharge by statistical method using only point rainfall data and water table fluctuation disregarding the fact that water table fluctuation may be result of recharge from other sources. In the present paper an attempt has been made to check the validity of statistical approach. Using the Green and Ampt infiltration equation and soil moisture characteristics of a known soil, the recharge due to several rainfall events has been determined and the consequent water table fluctuation has been determined using the Hantush's solution for water rise due to recharge from a rectangular spreading basin. Using the synthetic data of water table rise and rainfall values, a linear relation between rainfall and water table fluctuation has been established from which recharge due to rainfall has been estimated,. The recharge values computed by the two methods have been compared.
